What affects the rate of evaporation of water.Featured science projectScience project video
This experiment was performed to ascertain the factors that increase the rate of evaporation of water. The factors under examination for this experiment were the surface area of the body of water, air temperature and air pressure.
Difficulty: Elementary school
The efficacy of bioethanol fuelFeatured science projectScience project video
This science fair project was done to compare the performance of bioethanol against other types of fuel. The tests were done by comparing the energy produced, as well as the burning time of bioethanol, kerosene, diesel and gasoline.
Difficulty: High school
Fire resistant balloonsFeatured science projectScience project video
This experiment was performed to demonstrate how heat can be transferred from one surface to another by thermal conduction. The experiment was done by comparing the effect of fire on a balloon filled with air and one filled with some water.
Difficulty: Middle school
What affects the boiling point of water?Featured science projectScience project video
This science fair project was conducted to ascertain the various factors that determine the boiling point of water. The science project experiment involved comparing the effect of different amounts of water, different types of heating devices, different room temperatures and different heights above sea level, on the boiling point of water.
Difficulty: Middle school
Heat - Thermal conductivityFeatured science projectScience project video
This science fair project was conducted to evaluate how thermal conductivity varies in different types of metals. The tests were done with copper, aluminum and steel wires

How to make a steam powered rocket boatFeatured science project
A rocket works the same way. Hot gases and fire come out of the motor of a rocket. The gases coming out the nozzle at the bottom of the rocket come out in one direction. These escaping gases push the rocket in the opposite direction.
Difficulty: Elementary school
How to make a solar-powered ovenFeatured science project
The Florida Solar Energy Center conducted a research project on low-cost panel type solar ovens for the Dorothy Ann Foundation on behalf of Solar Household Energy, Inc. The overall purpose of the research project was to attempt to improve the performance, reliability and cost-effectiveness of low-cost solar cookers for use in developing nations.
Difficulty: High school
Analyse the different heat retention capabillities of straw, sand, paper and cloth
The purpose of this experiment was to find out the effect of different types of insulation on heat retention. My hypothesis is that sand will retain more heat than straw, sand, paper, cloth’ batting.
Difficulty: Middle school
Do different gases expand differently when heated?
The purpose of this experiment was to compare the amount of heat expansion in various gases. The information gained from this experiment will determine what temperature you need to keep your balloons at so that it can have more volume.
Difficulty: Middle school
